Heat pumps run cooling in summer and heating in winter, which means they accumulate runtime hours about 60% faster than a heat-only or cool-only system. That extra runtime is why heat pumps need a different maintenance cadence than a straight AC, and it is why most heat pump failures we see in SA are wear-out failures (capacitors, contactors, reversing valves, refrigerant leaks) rather than catastrophic breakdowns.
Every truck stocks the common heat pump failure parts, including capacitors, contactors, condenser fan motors, blower motors, refrigerant in all current formulations (R-410A, R-454B, R-32, plus R-22 for older systems), ignitors for dual-fuel hybrids, defrost boards, and reversing valve solenoids. 80% first-visit fix rate on repair calls.
Three Common San Antonio Heat Pump Failures We Diagnose
Heat pumps fail differently than straight AC systems because they have more parts working harder. The reversing valve, defrost board, and crankcase heater are all heat-pump-specific failure points. Here are the three failure modes we diagnose most often in San Antonio.
Reversing Valve Failure
SA Winter Failure
Refrigerant Leaks
Slow-Build Failure
Defrost Board Failure
Winter Morning Failure
Failure #1: Reversing Valve Stuck or Leaking (the SA winter failure)
The reversing valve switches the refrigerant flow between cooling and heating. When it sticks (mechanical jam) or develops a refrigerant leak (the solenoid coil bypasses), your heat pump runs but only cools, or only heats, or runs cold air in heat mode. Most common in 8-12 year-old heat pumps that have seen heavy SA summer runtime.
Repair
Solenoid coil replacement (in stock, $185-$285 total) or full reversing valve replacement (special order, $850-$1,400 total). We diagnose by checking the solenoid voltage with the system running in heat mode, typically 3 minutes on site.
Failure #2: Refrigerant Leaks (the slow-build failure)
Heat pumps run 60% more runtime hours than straight ACs, which accelerates refrigerant leak development at flare connections, Schrader cores, and evaporator coil micro-cracks.
Symptoms
Longer runtimes, weaker output (cool air in summer, warm air in winter), and rising electric bills. We use electronic leak detectors to locate the leak source and repair the leak before we top off refrigerant. Topping off a leaking system without finding the leak is wasted money.
Failure #3: Defrost Board or Outdoor Sensor Failure (the winter morning failure)
When SA dips below 40 degrees, the heat pump's defrost cycle kicks in periodically to melt frost off the outdoor coil. The defrost board reads the outdoor sensor and decides when to run defrost. When either fails, you see ice buildup on the outdoor unit, the unit short-cycles, or the unit runs in defrost too often (blasting cold air through your vents in heat mode).
Defrost board replacement
$245-$385 total. Outdoor sensor: $95-$165 total. Both are stocked on every truck.
Our Heat Pump Diagnostic and Repair Process
-
A real San Antonio team member answers. 10 seconds of triage, including what you are seeing, when it started, brand and approximate age, so the dispatcher routes the right technician with the right parts. We confirm the arrival window before we hang up.
-
Text message when the tech is en route, including a photo and name of the technician. No mystery dispatch.
-
Roughly 30-45 minutes on site for a heat pump diagnostic, slightly longer than a straight AC because we test both heating and cooling modes plus the reversing valve cycle. Refrigerant pressures checked against manufacturer spec, capacitor microfarad tested, contactor inspected, defrost cycle exercised, electrical draw measured, condensate drain verified. You see the readings. We do not quote a repair before we know what is actually wrong.
-
Verbatim parts and labor pricing before we touch anything beyond the diagnostic. The price we quote is the price you pay, no surprise upcharges, no parts markups discovered mid-job.
-
Every truck stocks the common heat pump failure parts. We finish the repair the same visit on 80% of calls. The remaining 20% are usually special-order parts like a full reversing valve assembly or a brand-specific compressor. We set the next-visit date before we leave and prioritize that follow-up.
-
Final commissioning check: pressures, temperature split (cooling and heating), defrost cycle, breaker draw. We log the readings on the service record. 30-day callback warranty: if the same problem returns within 30 days, we come back at no charge.
Heat pumps need two tune-ups a year, not one. Once in spring before peak cooling season, once in fall before heating season. The spring tune-up checks cooling-mode performance and refrigerant charge. The fall tune-up checks the heating cycle, defrost board, reversing valve operation, and dual-fuel changeover (if applicable). Skipping either tune-up cuts equipment life roughly in half compared to twice-a-year-maintained systems.
Heat Pump Maintenance and Tune-Ups in San Antonio
Spring Heat Pump Tune-Up, $49
Full cooling-mode inspection: refrigerant pressures and superheat/subcool, outdoor coil cleaning, evaporator coil inspection, condensate drain flush, capacitor microfarad test, contactor inspection, blower motor amp draw, temperature split verification, thermostat calibration, electrical safety check, filter check, and condensate pump verification if applicable. Roughly 60-75 minutes on site.
Fall Heat Pump Tune-Up, $59
Full heating-mode inspection: reversing valve exercise and verification, defrost board sensor calibration, outdoor sensor reading vs ambient, supplemental heat strip continuity if equipped, heating-mode pressures, dual-fuel changeover test if applicable, gas furnace inspection for hybrids (heat exchanger, ignitor, flame sensor, gas pressure), CO test on backup furnace. Roughly 75-90 minutes on site.

Frequently Asked Questions
How much does a heat pump repair cost in San Antonio?
Most common heat pump repairs (capacitor, contactor, defrost board, refrigerant leak repair, reversing valve solenoid coil) land between $185 and $685, parts and labor included. We provide a written estimate with verbatim pricing before any work starts. The $89 diagnostic fee is credited back when you approve the repair.
How often does a heat pump need maintenance?
Twice a year, once in spring before peak cooling season and once in fall before heating season. Heat pumps accumulate 60% more runtime hours than straight ACs because they run both heating and cooling, which means they wear faster. Skipping either tune-up cuts equipment life roughly in half.
Why is my heat pump blowing cold air in heat mode?
Most common cause: defrost cycle (normal during winter, lasts 5-15 minutes). If it persists longer, the reversing valve is likely stuck or the solenoid coil is bypassing. Less common: low refrigerant, faulty outdoor sensor, or the auxiliary heat strips are not engaging. We diagnose by exercising the reversing valve and checking solenoid voltage, typically 5 minutes on site.
Can you service my heat pump if it uses R-22?
Yes. R-22 is still available for service (production was phased out in 2020, but recycled stock is supplied for legacy systems). Current SA pricing runs $190-$260 per pound. If your system is leaking R-22, we will discuss whether ongoing service or replacement makes more sense.
Do you service the new A2L refrigerants, R-454B and R-32?
Yes. Federal regulations transitioned new heat pumps to A2L refrigerants starting January 2025. R-454B (Carrier, Bryant, Day & Night) and R-32 (Goodman, Heil, Tempstar) are stocked on every truck, and our technicians are A2L-certified per EPA Section 608.
